Timeplot is a DHTML-based AJAXy widget for plotting time series and overlay time-based events over them. Timeplot extends our existing Timeline widget to provide the ability to overlay time series over existing Timeline event data.
I have used Timeline a few times and I’ve loved it. I can’t wait to try out Timeplot. Plotting time-based events and time series data together is somehting missing in Swivel and Many Eyes. You will be able to plot a stock price chart with its news overlay like Google Finance. I’ve found the website stats example very interesting. Have you seen anything like that?
Why another charting tool? Timeplot FAQ answers:
- it doesn’t require any plugin to be installed in your browser
- it doesn’t require any software to be installed on the server
- it’s based on Timeline’s code so it’s naturally capable of reusing event data and mash it up with time series
- it’s highly modular: you can write your own time series processing algorithms or your own layout geometries and add them directly from your pages (without having to wait for us to add them).
- it’s open source software (under a BSD license)
- It allows the user to merge fields from different data sources, so that they are treated identically for sorting, filtering, and visualization. Fields are merged using simple drag and drop of field names.
- It provides an efficient means for the user to clean up data syntactically, homogenize data formats, and extract fields syntactically embedded within existing fields, all through the application of simultaneous editing.
- It supports faceted browsing to let users explore and identify subsets of data of interest or subsets of data that need alignment and clean up
There are many interesting talks during the 5 days conference. Tim Berners-Lee is there as plenary speaker, too!
How do people plan the days at a conference? Although I don’t go the conference I have checked the confabb. There are 5 entries of WWW2007, but it’s shame that none of them have sessions nor speakers information.
Lastly I want to quote this (again) by David Huynh
So, small data sets are a big deal
if we make them
usefully browsable, readily RE-usable, and so easy to publish.
I instantly thought I would use it to populate SIMILE Timeline.
First l looked for a practical source of data and I chose BBC’s Timeline of Alan Johnston to show support for him. I have created a spreadsheet manually, but I believe it’s worth doing. Here it is – Alan Johnston missing in a SIMILE Timeline widget.
Note that I used the BBC’s favicon link as icon for Timeline’s event object, which is shown in FireFox, but not in IE.
The TED (Technology, Entertainment and Design) launched the new website, which was also featured as “Giving Away Information, but Increasing Revenue” at New York Times. I am looking forward to exploring the new site and watching great talks again and again.
The innovative navigation in Flash showing groups of talks in different size is enjoyable. They also provide a simple list view.
Wouldn’t it be great if we could browse talks in SIMILE Exhibit? Is there any chance for them to make all talks’ meta data available in XML? Yahoo! Pipes could create a JSON feed for Exhibit from the XML.
Sorry for not having any implementation here, but just throwing an idea first.
BBC has huge news archives and many interesting Timeline pages:
More here. They are all static HTML pages. However, they made great effort to visualize/mashup some of them using Flash.
Yahoo! Pipes is so exciting.
Personally I prefer Exhibit to Tabulator because the data is stored in JSON files.
Exhibit data models are RDF graphs; these data models can be converted into RDF without loss. However, the Exhibit data model is a sub-model of RDF, as described below. This design choice allows for specialized, simple syntax (based on JSON) for rapid authoring. For simple, small data sets, we believe that Exhibit data models are sufficiently expressive. An Exhibit data model contains a set of items, each having a type and several properties.
